What causes toilet bubbling when shower runs in South Gilbert homes?
Negative air pressure in drain-waste-vent (DWV) system caused by a main sewer line blockage or obstructed rooftop plumbing vent stack forcing trapped sewer gases upward through toilet trap water. In South Gilbert, water hardness of 15-22 GPG and high static pressure accelerate these mechanical issues.
Can this issue cause permanent damage if left unaddressed?
Yes. Hidden plumbing leaks or sewer line back-pressures can erode soil beneath foundations, ruin drywall, and trigger costly microbial growth within 24-48 hours.
